I don't see any nfs updates for 4.2, but I'm wondering if there's a fix.
Anyone else run into this?

Hi Tom,
Only QNX 4.25 with TCP/IP 5.10 is supported now. Please, check out the QNX 4
Product Suite CD 2011:

It appears the server is already on 4.25.
(I booted that cd and tried to install, but it doesn't actually install
anything except the boot loader, even after checking all the packages.)

Hi Tom,
We can't reproduce this issue. How do you launch portmap, nfsd, mountd, etc.
Please, send us:
# sin ar > sin_ar.txt
How do you mount NFS share under Linux? Which command line options do you use?

Thanks for looking into it more. (I wasn't able to get that cd to
actually install any packages. Maybe our license #s are too old.)
The bug is rarely triggered - weeks between occurrences.
On the qnx side, /etc/config/sysinit.1 runs /etc/config/start.network.sh
+nfs, which contains:
/usr/ucb/portmap &
if test "$1" = "+nfs"
then
sleep 1
/usr/ucb/nfsd 4 &
sleep 1
/usr/ucb/mountd &
fi
/etc/exports contains /tmp/bol
On the linux side: mount -o rw,soft,nfsvers=2 node1:/tmp/bol /mnt/bol

Hi Tom,
You've launched NFS server in UDP mode. Also you've used "soft" option on
mount. These may potentially damage NFS data.
Is the nfsd working correctly in TCP mode? Launch the nfsd with the following
command:
# /usr/ucb/nfsd -t 0,0,4 &

Neither should cause file corruption (file is written out once on qnx
side, then eventually read by linux side). I ran tcpdump to be sure that
qnx is using udp checksums and it is. It is possible the bug is only in
the udp path of the nfsd code. I'll see if we can try tcp mode in some
production sites. We're not getting any io errors, so soft vs hard mount
shouldn't matter.
